BACKGROUND OF THE INVENTION

The present invention relates to the discovery of a new and distinct cultivar of ornamental blueberry (Vaccinium (angustifolium×myrsinites)×corymbosum hybrid) and referred to as ‘ZF08-095’, as herein described and illustrated.

The new blueberry plant variety ‘ZF08-095’ was selected in Lowell, Oreg. in 2008. ‘ZF08-095’ is an ornamental variety intended for nursery, landscape, and home garden use. The variety is a semi-dwarf with a round shape and shiny dark green leaves that turn shades of purple, red, and yellow in the fall. ‘ZF08-095’ has attractive fruit that ripens from red to black in mid to late July, and has a mild, sweet flavor.

Pedigree and History: The new blueberry plant originated from a 1988 controlled cross pollination of ‘JU 60’ (female parent, unpatented) by ‘US 702’ (pollen parent, unpatented). ‘ZF08-095’ was selected from a seedling population grown in Oregon from seed obtained from the Fruit Laboratory, USDA-ARS, Beltsville, Md. The cross that produced the seed, which was made in 1988, involved three tetraploid species of Vaccinium: (V. myrsinites×V. angustifolium)×[V. corymbosum×(V. myrsinites×V. angustifolium)]. The seedling was first selected from a high density field planting in the summer of 2008. ‘ZF08-095’ was propagated using traditional techniques and has been planted in replicated trials since 2009. The original trial plot was removed in 2011, and all subsequent observations have been collected on a second plot established in 2010. ‘ZF08-095’ has been observed in plots of 2-3 plants in 2009, 2010, 2011, and 2012. In comparison to the female parent, ‘JU-60’, ‘ZF08-095’ has a leaf covered with less wax, giving ZF08-95 a more shiny appearance to the leaves. In comparison to the pollen parent, ‘US-702’, ‘ZF08-095’ has a much shorter plant height, smaller leaves, and shorter internode spacing.

The new variety can be compared to ornamental variety ‘Burgundy’ in that ‘ZF08-095’ has smaller, darker colored, shiny leaves, and larger berries that are darker in color.

The new variety can be compared to ornamental variety ‘Sunshine Blue’ in that ‘ZF08-095’ has darker fruit and smaller, shiny, dark green leaves as well as a more compact growing habit.

The new blueberry plant variety ‘ZF08-095’ has maintained its distinguishing characteristics throughout successive asexual propagations. The variety has been repeatedly asexually reproduced through softwood cuttings in Lowell, Oreg., and the clones are phenotypically identical to the original plant.

SUMMARY OF THE INVENTION

The new blueberry plant variety ‘ZF08-095’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed in Lowell, Oreg., and are determined to be the unique characteristics of the new blueberry plant variety ‘ZF08-095’:

• • 1. Uniform, round shape.
  • 2. Dark blue to black fruit
  • 3. Shiny leaves
  • 4. Red, yellow, and dark purple fall foliage.

BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of ‘ZF08-095’. The data which defines these characteristics was collected from asexual reproductions of the original selection. Dimensions, sizes, colors and other characteristics are approximations and averages set forth as accurately as possible. The plant history was taken on plants that were three and four years old, and the descriptions relate to plants grown in the field in Lowell, Oreg. Color designations are from “The Pantone Book of Color” (by Leatrice Eiseman and Lawrence Herbert; Harry N. Abrams, Inc., Publishers, New York, 1990). Where the Pantone color designations differ from the colors in the photographs, the Pantone colors are accurate.
